Pigmented contact dermiatitis is a disease resulting from recirrent contact dermatitis due to hypersensitivity to cosmetic components, which produces secondery bizarre dark brown hyperpigmentation. Histological examinaition of this condition reveals liquefaction degeneration of the basal cells of the epidermis and melanopbages in the upper dermis. We report a case of pigmented contact dermatitis from musk tibeten, which was diagnosed by the histological examination, the patch and photopatch tests. Residul hisperpigmentation was seen on the region of the patch testing.

To evaluate the role of capsular polysaccharide (CPS) as a virulence factor, the interaction of V. vulnificus with mouse peritoneal macrophages and serum, which are involved in the clearance of bacteria from blood and other tissues, were examined. In this study, MO6-24/0 (wild strain; hemolysin- and capsule-positive), MO6-24/I' (acapsular spontaneous mutant), CVD 752 (acapsular transposon mutant), and CVD 707 (hemolysin-negative and capsule-positive mutant) were used. The strain with CPS (MO6-24/0 and CVD 707) were more resistant to phagocytosis by mouse peritoneal macrophages compared with acapsular strains (MO6-24/T and CVD 752), and the resistance to phagocytosis was not changed by serum opsonin in the capsular strains. Acapsular strains were more susceptible to serum bactericidal activity than the capsular strains through the classical complement pathway. MO6-24/0 strain were detected in blood, spleen, liver and lung at 4 hours after intraperitoneally infection, whereas CVD 752 were not detected. All tested strains could induced the transcription of inflammatory cytokine gene such as IL-1, IL-6, IL-10 and TNF-u, and their inductions were not decreased by cytochalasin B treatment. This results demonstrate that CPS of V. vulnificus plays an important role in V. vulnificus infection through interfering nonspecific host defense system such as blood clearance and phagocytosis.

Subcutaneous panniculitic T-cell lymphoma(SPTCL) is a rare subtype of peripheral T-cell lymphoma that clinically and histologically mimics benign panniculitis. It represents subcutaneous nodules predominantly on extremities and trunk and hemophagocytic syndrome almost leading to death. Recent reports suggest that cytophagic histiocytic panniculitis(CHP) and SPTCL may span a clinicopathologic spectrum in which there is a natural disease progression from CHP to SPTCL. We report a 41-year-old Korean man who presented with recurrent tender erythematous subcutaneous nodules on the buttock and extremities for 13 years history. There was no hepatosplenomegaly or lymphadenopathy. Laboratory data revealed mild anemia, leukopenia, and elevated alanine transferase. Epstein-Barr virus(EBV) serological values evidenced chronic active infection. His skin biopsy specimen showed lobular panniculitis with atypical lymphohistiocytic inflammatory infiltrates. The inflammatory infiltrates expressed CD45RO, CD3, CD4, CD8, and CD68. But CD20 and CD56 were negative. In situ hybridization studies for the EBV genome showed negative finding. This case presents SPTCL that had eluded diagnosis for a long time. It also suggests the importance of continued follow-up with repeated biopsy, in case of long course of recurrent tender erythematous nodules and histological lobular lymphocytic panniculitis.
